The tactics used by the Gallian army prove effective, and like Flaguerre before it, Mugill falls to claw and steel. Before Begnion can react, the laguz overwhelm the remaining border defenses and cross into the Telgam region. With both defensive keeps overrun, Telgam falls like ripe fruit at the feet of the Laguz Alliance. Inspired by their success, the alliance takes advantage of this momentum to strike toward the very heart of the Begnion Empire. Dukes Gaddos and Seliora are horrified by the speed of the laguz advance. Banding together with the landowning nobles of the northern territories, the mass their armies in Seliora to oppose the Gallian assault. Using the Ribahn River, a tributary of the mighty Miscale, as a defensive front, the Begnion forces make their camps along its western bank in the Sestohl Plains.

To the Greil Mercenaries' surprise, Ranulf and the Laguz have devised a plan to halt Begnion's central army, to avoid being sandwhiched as they march towards the capitol. The Shipless Pirates, the Bird Tribe, will steal the army's supply before they can ground and catch up to the laguz army marching onward towards the capitol.

At the end of the battle, the Begnion Central Army is on the Laguz Alliance's tail, spawning the horrible thought that Tibarn failed and is now dead. Ranulf willingly attacks his own general, Skrimir, in hopes of swaying his decision to fight and instead retreat. Ranulf's bones are broken and Skrimir, despite his hesitation to do so, orders a retreat on Ranulf's behalf.
